Patent DE-2634939-A1 (DE)
Title: Sealed lubrication system for bearing - has lubricant pressurised by diaphragm acted on by compressed air
Inventor: OHLBERG KARLHEINZ
IPC: F16C33/66
Filed: 1976-08-04
Abstract: The lubricating system for bearings comprises a bearing housing (14) having a chamber divided by an elastomeric diaphragm (6). At one side of the diaphragm the chamber is open to the bearing(s) (4). At the other side, the chamber has a duct (7) to atmosphere. Air pumped through that duct bulges (15) the diaphragm towards the one side and is retained by a check valve (8). Grease is injected (10) through the bearing into the one side of the chamber and bulges the diaphragm the opposite way. The air is then let out by opening a screw closure in another duct between the other side of the chamber and atmosphere. The screw closure may be replaced by a filteR.

Title: Beer brewery wort boiling system - which saves heat energy by heating lower pressure stages with vapour from higher pressure stages
Inventor: JANOSIK MANFRED DIPL ING
IPC: C12C7/22
Filed: 1976-08-04
Abstract: The wort in beer breweries is boiled at different pressure stages. Only the pressure cooker of the highest pressure stage is heated by extraneous energy (steam, hot water, hot oil, furnace) which is adequate to cover the heat losses and to heat the wort to boiling temp. Enough water is evaporated here to supply all lower pressure stages with heat by condensation of the steam. Arrangement recovers all heat from the condensation of vapours. The heat energy consumption for the brewing vat can be reduced to one-third of its usual value. The pollution of the environment by brewing vat fumes is also reduced by the same amount.

Title: Ice cube tray which is rotated for emptying - has thermostat controlled switch supplying power to heating elements in tray and internal partitions
Inventor: GRAU GEB DRUECK URSULA
IPC: F25C1/04
Filed: 1976-10-25
Abstract: The ice cube tray has partitions determining the size of cubes. The walls of the tray (5) or the partition walls can be heated for short period for facilitating removal of the ice. A resistance heater system is used which is connected by an automatic switch to an electric power source. This switch is connected to a thermostat which ensures that heater can be connected only after ice cubes have been formed. The tray can be revolved about its axis in the refrigerator through half a circle for emptying.

Title: Measuring underground fuel tank contents - using flow meter at initial filling to provide pulses for electronic processor
Inventor: LEMKE ERICH
IPC: G01F23/24
Filed: 1977-03-02
Abstract: An underground fuel tank lies on its side at an angle to the horizontal. A feed pipe permits the tank to be filled with fuel. The volume of fuel transferred to the tank is measured by a flow meter. The flow meter transmits impulses to an electronic processor which simultaneously receives a liq. depth signal by way of a connection from a probe within the tank. In this way, an indication of the relationship between the probe signal and the volume of liq. can be derived without taking account of the shape of the tank or its elastic deformation. The processor may also receive an input from a temp. probe to correct the signal transmitted to an indicator.

Title: Travelling toy car headlamp switch system - includes remotely operated switch arm with lug engaging star wheel on passing car
Inventor: NEUHIERL HERMANN DR
IPC: A63H18/02
Filed: 1977-08-01
Abstract: A track for toy vehicles has a slot down the middle through which projects a lug (32) which in the raised position, knocks against a tooth on a ratchet wheel (12) on the car to operate a switch controlling the headlamps, as the car travels past. This lug is attached to an arm (33) which is pushed up by a swinging lever mounted above it, which can be moved directly by a lever at the side of the track, or by a Bowden cable device. The arm is held in a lowered, inoperative position by a spring (34) and the swinging arm pushes the arm upwards against this spring. This rotates the ratchet wheel as the car passes, so that a contact (16) on a leaf spring (14) is moved against or away from another contact on the ratchet wheel.

Patent DE-2801358-A1 (DE)
Inventor: SCHNEIDER HANS-ULRICH
IPC: H02K11/20
Filed: 1978-01-13
Abstract: A fluid sensor which is provided with connecting wires for a control circuit is fitted inside the motor housing at the point which is lowest when the electric motor is in use. The fluid sensor comprises a holder, for example a lamp-wire terminal, in which there is mounted a PTC thermistor bead or an NTC thermistor bead for detecting a non-conductive fluid, which has penetrated into the housing, on the basis of a temperature change. In order to detect a conductive fluid on the basis of a resistance change, the holder can have open contact electrodes which the fluid touches, for which purpose the lamp-wire terminal can be used on its own. In consequence, it is possible to achieve operationally reliable, space-saving and cost-effective detection of electrically conductive fluids or non-conductive fluids inside the electric motor. <IMAGE>
